Poland's syndrome and recurrent pneumothorax: is there a connection?

Aim. To investigate the possible connection of Poland's syndrome with the presence of lung bullae and, thus, with an increased risk for recurrent pneumothorax. Patients-methods. Two male patients, aged 19 and 21 years respectively were submitted to our department after their second incident of pneumothorax. Both had Poland's syndrome (unilaterally hypoplastic chest wall with pectoralis major muscle atrophy) and both had multiple bullae to the ipsilateral lung based on CT findings. The patients were treated operatively (bullectomy, lung apicectomy, partial parietal pleurectomy and chemical pleurodesis) due to the recurrent state of their pneumothorax. Results. The patients had good results with total expansion of the affected lung. Conclusions. Poland's syndrome can be combined with ipsilateral presence of lung bullae, a common cause of pneumothorax. Whether this finding is part or a variation of the syndrome needs to be confirmed by a larger number of similar cases

Decision Agriculture

In this chapter, the latest developments in the field of decision agriculture are discussed. The practice of management zones in digital agriculture is described for efficient and smart faming. Accordingly, the methodology for delineating management zones is presented. Modeling of decision support systems is explained along with discussion of the issues and challenges in this area. Moreover, the precision agriculture technology is also considered. Moreover, the chapter surveys the state of the decision agriculture technologies in the countries such as Bulgaria, Denmark, France, Israel, Malaysia, Pakistan, United Kingdom, Ukraine, and Sweden. Finally, different field factors such as GPS accuracy and crop growth are also analyzed

Quantitative proteomics of delirium cerebrospinal fluid

Delirium is a common cause and complication of hospitalization in older people, being associated with higher risk of future dementia and progression of existing dementia. However relatively little data are available on which biochemical pathways are dysregulated in the brain during delirium episodes, whether there are protein expression changes common among delirium subjects and whether there are any changes which correlate with the severity of delirium. We now present the first proteomic analysis of delirium cerebrospinal fluid (CSF), and one of few studies exploring protein expression changes in delirium. More than 270 proteins were identified in two delirium cohorts, 16 of which were dysregulated in at least 8 of 17 delirium subjects compared with a mild Alzheimer's disease neurological control group, and 31 proteins were significantly correlated with cognitive scores (mini-mental state exam and acute physiology and chronic health evaluation III). Bioinformatics analyses revealed expression changes in several protein family groups, including apolipoproteins, secretogranins/chromogranins, clotting/fibrinolysis factors, serine protease inhibitors and acute-phase response elements. These data not only provide confirmatory evidence that the inflammatory response is a component of delirium, but also reveal dysregulation of protein expression in a number of novel and unexpected clusters of proteins, in particular the granins. Another surprising outcome of this work is the level of similarity of CSF protein profiles in delirium patients, given the diversity of causes of this syndrome. These data provide additional elements for consideration in the pathophysiology of delirium as well as potential biomarker candidates for delirium diagnosis

Investigation of Spatial Variability of Air Temperature, Humidity and Velocity in Cold Stores by Using Management Zone Analysis

The main objective of this research was to determine spatial variability of ambient temperature, relative humidity and air velocity in a cold storage using management zone analysis methods. Ambient temperature, relative humidity and air velocity of an experimental cold store were measured using 36 temperature-relative humidity sensors and air velocity measurement probe. Sensor installation was performed on grid scale at three levels (base, middle and top) such as to monitor the storage conditions in the cold store. The measured data were analysed by MZA software which performed fuzzy clustering to delineate the full cold storage, half full cold storage and empty cold storage. In addition, Surfer mapping software was utilized to create the maps of the measured parameters. The results indicated that there is significant spatial variation of the basic storage parameters such as ambient temperature, relative humidity and air velocity in the cold storage, which denotes the significance of management zones delineation in these facilities so as to maximize the storage

Mobbing: Elements-Causes-Effects

Aim: Τo investigate the Mobbing phenomenon as well it’s causes and effects, Material and Methods: We investigated the Mobbing by reviewing previous international research over mobbing. The research material was accumulated after thoroughly examining former studies and reviewing the existing literature, as it was found in the bibliography, data bases, academic libraries, academic journals and the internet. Results: Through the research we tried to define this phenomenon and at the same time to study the constituent elements as well as it’s causes and effects. Finally, we conducted a literature review from previous research in order to investigate this phenomenon and its factors. Conclusions: The current study has concluded that mobbing sadly negatively affects the recipient by creating both direct and indirect effects on various aspects of his daily life, one of which is the workplace.</jats:p

Mobbing In The Workplace : A Literature Review

Aim.: Τo investigate the Mobbing phenomenon in the workplace, Material And Methods: We investigated the Mobbing by reviewing previous international research over mobbing.

Administration in the Operating Room

When referring to the operating room of a health organization, we know in advance that it is a department that is accompanied by multiple requirements and high responsibilities from all the human resources that staff it. Its high demands and great responsibilities result, on the one hand, from the criticality of the state of health of each patient and from the special characteristics that accompany it, from the existing risk of complications during the operation, and on the other hand, from the diversity from which characterizes the team of human resources that staffs the operating room. More specifically, the operating room consists of the director, the head, the head of the department, the medical staff, the nursing staff, the technical department and the administrative department. The medical department is divided into the competent surgeons and anesthesiologists. The smooth operation of this department requires effective cooperation and communication between all members of the surgical team. Clear definition of roles and responsibilities plays a key role in avoiding unwanted conflicts between surgeons, anesthesiologists and nurses. The director and the head of the operating room, as well as the head of the department, play a leading role in avoiding these conflicts. For this reason, these jobs must be staffed by employees who, in addition to technical skills, have administrative and communication skills. The wider part of the operating room of a health organization should be staffed by health professionals who have increased experience in their specialty and have all the necessary knowledge, in order to make a proper preoperative assessment of the patient’s health condition and timely and effective anticipation and treatment problems that may arise during the surgical procedure.</jats:p
